Introduction This 2014 modeling platform includes all criteria air pollutants and precursors (CAPs), two groups of hazardous air pollutants (HAPs) and diesel particulate matter. The first group of HAPs are those explicitly used by the chemical mechanism in the Community Multiscale Air Quality (CMAQ) model for ozone/particulate matter (PM): chlorine (Cl), hydrogen chloride (HCl), benzene, acetaldehyde, formaldehyde, methanol, naphthalene. The second group consists of 51 HAPs or HAP groups (such as polycyclic aromatic hydrocarbon groups) added to CMAQ for the purposes of air quality modeling for the 2014 National Air Toxics Assessment (NATA). The latter five HAPs in the first group are also abbreviated as NBAFM in subsequent sections of the document. A list of all HAPs and diesel species in this modeling platform is in Appendix A. This platform is called the “2014 NATA-Based Platform, version 7.1” (2014v7.1) because it is a HAP-CAP used primarily for NATA. Here, “version 7.1” denotes an evolution from the earlier versions of the 2014-based platform. Version 7.0 supported the initial modeling for NATA. A version subsequent to that supported a CAP application of the 2014 NEI. Both platforms were the starting point for a number of the ancillary (non-emissions) data files for version 7.1. The 2014v7.1 platform was used to support the 2014 NATA, the focus of which is multipollutant modeling of HAPs and CAPs using CMAQ version 5.2 multipollutant. The CMAQ modeling domain includes the lower 48 states and parts of Canada and Mexico. The 2014 NATA also utilizes the American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD), which is an air dispersion modeling system, for all NEI HAPs (about 130 more than covered by CMAQ) across all 50 states, Puerto Rico and the Virgin Islands. Emissions preparation for AERMOD is discussed elsewhere. Data Summary: U.S. EPA National Emissions Inventory Version 2. 2014 Modeling Platform version 7.1 Note:The datasets are on a Google Drive. The metadata associated with this DOI contain the link to the Google Drive folder and instructions for downloading the data.These packages contain the CMAQ-ready, gridded, speciated hourly emissions files for 2014 including 15 days of spinup days.

CMAQ model-ready emissions generated using these packages with SMOKE v4.5 should be identical to those used in EPA's 2014v7.0 platform.
